# Which data service to buy for redistributable data?

This is a follow-up to my previous question regarding anyone whom wanted to 'donate' data.

So far no one has stepped up (learning more about buying and selling data, I realize that I'm going to have to buy the data if I want to re-sell it, or give it away for that matter - re: licensing agreements?)

So I'm trying to determine a good source for data with a relatively flexible licensing agreement. So far the first place I've found is the CME's distributor's service @ ~$12,000/yr starting. If you sell historical data, know of data-feeds, etc., please let me know. I'll add it to this list, and we can discuss the pluses and negatives. - add comment ## 3 Answers I think you're addressing the wrong people. What I'd do is to talk to the data vendors' marketing departments, much like I'm sure http://www.wikiposit.org/ has done. Tell them you would like to offer (an excerpt of) their data, in a unified/post-processed form, you would be willing to include links back to their sales website, or praise the vendors somehow, e.g. have a voting system for the quality of the data. I'm not a data vendor but I'm sure as long as you make it look like that's the best form of advertising they've ever had you should be able to negotiate a licensing model that allows you to at least show the data on your website. I imagine this works particularly well with smaller or niche data providers. - thanks! that sounds like a plan. There are a lot of them out there- so that's why I posted it up here to see if I could get some recommendations! – jordan.baucke Jul 8 '11 at 19:50 add comment xignite seems like a cheaper option for historical data at around$6,000 per year. I am not a client (yet) so I can't give my opinion but it looks good to me. They have a long list of services, a free trial period and interesting pricing model based on the number of queries you send them. If you do use them, let us all know.

I'm using xignite and have for a couple years now. I think they're pretty good. They do seem to have the most flexible licensing agreement that I've come across. I've used a few of these services over the years. –  Dave Jul 13 '11 at 16:04
